In some embodiments, computer readable medium facilitates transactions in massively multiplayer online games. The computer readable medium can include executable instructions for execution by one or more processors to receive data to perform a transaction between participants associated with the synthetic environment. The executable instructions also can be configured to transact an exchange of a first subset of game data for the first participant and a second subset of the game data for a second participant. The exchange of subsets of the game data between the first participant and the second participant can occur in the common process.

BRIEF DESCRIPTION OF THE INVENTION

Embodiments of the invention relate generally to computer-based simulations and synthetic environment generation, and more particularly, to a system, a computer-readable medium, a method and an apparatus for implementing transactions associated with synthetic environments in a distributed architecture that, among other things, introduces dynamic content to implement a portion of a synthetic environment.

BACKGROUND OF THE INVENTION

Traditional techniques for designing and simulating computer-generated environments, such as virtual worlds in massively multiplayer online (“MMO”) games, do not readily facilitate the efficient development and production of new or modified virtual worlds. Moreover, conventional game platforms for generating virtual worlds further impede the development and production of virtual worlds, especially with respect to massively multiplayer online games. Generally, conventional game platforms use a set of game servers to create a virtual world, with each additional set of games servers being used to create a copy of the virtual world. Such copies are typically referred to as “shards.” Conventional game platforms routinely divide the geography of each virtual world into partitions, and allocate one game server to generate each single partition. A game server that is configured to generate a partition of a virtual world is commonly referred to as an “area server.” Further, some conventional game servers are monolithic, which means that all the game processes for generating a partition for a virtual world are instituted in a single process and/or server. While functional, there are a variety of drawbacks associated with conventional game platforms, as well as the traditional approaches to developing computer-generated worlds.

A drawback for some conventional game platforms is that they allocate one game server for a partition of the virtual world. As such, the game server and its functionality are usually linked directly to the partition and its activities. The performance of a geographically-linked game server, therefore, is a function of the number of players at that partition as well as the kinds of activities being performed there. Further, conventional game platforms that use monolithic game servers are somewhat limited by their inability to adjust their hardware capabilities to meet increases in demand. So, as more players move to a specific partition, the game server that supports that partition becomes increasingly burdened. This, in turn, limits the number of players that can interact with the corresponding virtual world partition. As a remedy, some massively multiplayer online games operate to migrate players off game servers that are heavily populated to game servers that are relatively less populated. This may significantly impact player experience.

Yet another drawback to traditional game platforms is that each game server usually has a separate process space for generating a virtual world partition than the other game servers in the same virtual world. It is not uncommon that players interact across a geographic boundary that demarcates two virtual world portions. As such, difficulties arise due to partition boundaries and conventional game platforms generally require computational resources to try to manage cross-partition interactions. For example, a game server associated with one player in one partition generally requires some sort of tracking functionality to track the interactions of that player with other players in other virtual world partitions. As another example, consider that computational resources are generally required to maintain players as proxies in different process spaces. Traditionally, implementing players as proxies requires converting one representation of player-specific information for one virtual world partition, such as a character identifier, into another representation for use with a separate process space for another virtual world partition. Further, game servers usually communicate among themselves about player interactions using, for example, remote procedure calls, which increase the complexity of communications as well as latency for cross-partition interactions between different memory spaces.

A further drawback to conventional game platforms is that players (or proxies of players) that interact across different virtual world partitions can readily disrupt transactions to unjustly enrich themselves. To illustrate, consider that a first player at one virtual world partition offers to exchange a weapon for gold possessed by a second player at another virtual world partition. Next, consider that the first player receives the gold, but before surrendering the weapon, the first player breaks the connection between the game servers at the different virtual world partitions. As a result, the first player will receive the gold without exchanging the weapon.

One drawback to using monolithic game servers is that if one of the game subprocesses, such as a physics process, of a monolithic game server falters or shuts down, then the entire game server in which the game subprocess resides is also susceptible to faltering or shutting down.

There are other drawbacks to using current client-server architectures to design and simulate computer-generated environments for massively multiplayer online games. Consider that along with the development activities required to create new content for new or modified virtual worlds, game designers and developers also regularly modify executable instructions to accommodate the new content and its data. Modifying executable instructions usually increases the development time, especially during quality assurance and reliability testing to weed out bugs and other problems. Further, massively multiplayer online games commonly require the modified executable code to be downloaded to a client prior to interacting with the new content. For instance, it is not uncommon for massively multiplayer online game platforms to implement large data downloads (e.g., 250 MB), which can include the modified executable code.

In view of the foregoing, it would be desirable to provide a system, a computer-readable medium, a method and an apparatus for generating synthetic environments in a distributed architecture to, among other things, introduce dynamic content into the synthetic environments, and to further provide for efficient development and production of new or modified synthetic environments.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION

FIG. 1A depicts a system for generating synthetic environments in accordance with at least one embodiment of the invention. One example of such a system is a synthetic environment generation platform 100, which include nodes (and node processes) that are networked together to generate a synthetic environment with which clients 150 interact. Synthetic environment generation platform 100 represents the server-side structure and/or functionality in a client-server network architecture, and clients 150 represent the client-side structure and/or functionality. The nodes include game subprocess servers 104, databases 112 and game management servers 122, all of which are coupled together by a network 115, to respectively implement game subprocesses 102, databases processes 110, and game management processes 120. Game subprocesses 102 can include more or fewer than subprocesses 102 a, 102 b and 102 c. As shown, game subprocess servers 104 are arranged in a distributed arrangement relative to at least game management servers 122, thereby separating game subprocesses 102 from game management processes 120. In at least one embodiment, game subprocess servers 104 a, game subprocess servers 104 b, and game subprocess servers 104 c can be configured to operate as physics servers, artificial intelligence servers, and transaction servers, respectively, or as any other game-related subprocess. Further, synthetic environment generation platform 100 is configured to implement a quasi aggregated process space 152 that can be shared either among game management servers 122, or among synthetic environment generation platform 100 and other similar synthetic environment generation platforms 100 (not shown), or both, according to various embodiments.

By distributing game subprocesses 102 a, 102 b and 102 c separately from game managements processes 120, game management servers 122 operate independently, thereby making them less vulnerable to deteriorations in performance of any of game subprocess servers 104. Thus, hardware and software failures can be localized to a specific game server subprocess 102, thereby enabling expedited problem identification and resolution, often without interrupting the game management processes 120. This allows clients 150, such as client 150 a and client 150 b, to continue interacting with a synthetic environment without being interrupted by problems occurring with game subprocess servers 104. In addition, distributed game subprocesses 102 a, 102 b and 102 c promote independent scaling in the amount of game subprocess servers 104 that can be brought online to sufficiently provide an appropriate amount of game subprocesses 102 a, 102 b and 102 c. For example, if a synthetic environment requires additional artificial intelligence, then additional artificial intelligence servers can be brought online independent of the needs of other game subprocesses 102, such as physics processes. Thus, an appropriate amount of hardware and software can be implemented to facilitate synthetic environment generation for any number of clients 150 interacting with the synthetic environment generated by synthetic environment generation platform 100. Further, quasi aggregated process space 152, which is shared with other similar synthetic environment generation platforms, facilitates inter-platform (i.e., cross-shard) interactions, thereby providing for improved communications and more secure transactions, among other things.

Game management servers 122 are each configured to collaborate with game subprocesses 102 and databases processes 110 to generate a synthetic environment with which a participant interacts. As such, game management servers 122 are configured to manage a number of participants associated with clients 150 in their interactions with the synthetic environment. Note that game subprocesses 102 can be scaled accordingly to support the number of clients 150. In various embodiments, clients 150 can be distributed across multiple game management servers 122, rather than being restricted to one game-generating process. To illustrate, consider that client 150 a can interact with game management server 122 a and client 150 b can interact with game management server 122 c. While clients 150 a and 150 b interact with different game management processes, they can share a quasi aggregated process space 152, regardless of the synthetic environment with which clients 150 a and 150 b interact. In one embodiment, clients 150 a and 150 b can share quasi aggregated process space 152 as a common process space. As such, cross-synthetic environment interactions can readily occur. In some embodiments, game management servers 122 can operate to validate an action requested by a particular participant, thereby authenticating that the participant has rights to modify game data. In at least one embodiment, game management servers 122 a to 122 n maintain the game data representing interactions by clients 150 with the synthetic environment in a read-only form. As such, the game data cannot be manipulated to corrupt transactions that might otherwise unjustly enrich a participant.

In one embodiment, game subprocess servers 104 a can be physics servers, which can be configured to process movement and collision activity, such as for a participant in a synthetic environment. For example, physics server 104 a can process physics-related events, such as collision detection, rigid body movement, and the like. Game subprocess servers 104 b, according to at least one embodiment, can be artificial intelligence servers, which can be configured to provide artificial intelligence to simulate, for example, movement by non-player characters (“NPC”) in a synthetic environment.

In various embodiments, game subprocess server 104 c can be a transaction server, which can be configured to manage transactions among participants to ensure the transactions are atomic. That is, game subprocess server 104 c can operate to ensure that all parts of a transaction occur, or all do not occur, thereby guaranteeing that game data stored in database processes 110 are not updated unless all parts of the transactions succeed, thereby reducing loop-holes for participants to seek unjust enrichments. The transaction server is the game authority that ensures that an activity is completed correctly for both participants, or is failed by both participants. In one embodiment, all servers in synthetic environment generation platform 100 are read-only except game subprocess server 104 c (as a transaction server). Thus, a transaction server—as game subprocess server 104 c—can operate as a single authority for transacting game data (i.e., it is authorized to modify game data). In at least one embodiment, a transaction server constituting a game subprocess server 104 can be configured to implement quasi aggregated process space 152 as a unitary process space, thereby enabling participants to engage game management servers for different synthetic environments while transacting within a emulated common process space provided by quasi aggregated process space 152.

In operation, clients 150 a and 150 b generate requests to cause representations of the participants, such as avatars, to modify game data in game management processes 120. As used herein, the term “game management server,” at least in one embodiment, refers to a computing device and/or a process that manages interactions of participants with a synthetic environment. For example, a game management server can accept input from clients 150, and, in response, collaborate with game subprocesses 102 and database processes 110 to generate modified game data, which represents a modified synthetic environment based on client interaction, for transmission back to clients 150 a and 150 b. As used herein, the term “game subprocess server,” at least in one embodiment, refers to a computing device and/or a process that performs a subset of a game process, such as a physics server and an artificial intelligence server, the results of which are used by a game management server.

As used herein, the term “node,” at least in one embodiment, refers to computing devices and/or processes that influence the generation of a synthetic environment, such as a server, a client, a database, and the like. As used herein, the term “game data,” at least in one embodiment, refers to at least a subset of data relating to the generation of a synthetic environment. Game data can include map data to, for example, generate a terrain of a synthetic environment. Game data can also include the state of a participant, including character data, inventory data (e.g., weapons data), bank data, synthetic home data, award data, and the like. As used herein, the term “synthetic environment,” at least in one embodiment, can refer to a virtual world (or a portion thereof) that is a computer-based simulated environment intended for its participants to inhabit and interact via, for example, avatars. A synthetic environment can also refer to a shard or a persistent world (or a portion thereof), which is a virtual world that progresses without or without participant interaction. As used herein, the term “participant,” at least in one embodiment, refers to either a player, or a two or three-dimensional graphical representation (e.g., an avatar) representation of the player, or both. A participant can also refer to a client with which the player interacts. As used herein, the term “quasi aggregated process space,” at least in one embodiment, refers to a memory space allocated for an application and/or implemented for executing instructions by a processor (e.g., one or more central processing units (“CPUs”)), whereby the memory space is configured to behave as an aggregated, common process space for certain types of data, and is further configured to behave as separate process spaces for one or more other types of data.

Note that game subprocess servers 104 and game subprocesses 102 can be configured to implement any other game-related processes to facilitate, for example, massively multiplayer online gaming (“MMO”) in accordance with other embodiments. Further, one or more databases 112 a to 112 c can be configured to store data, for example, to generate the synthetic environment, among other things. As such, one or more databases 112 a to 112 c can store account data relating to participant accounts, statistical data, audit data, game data, and the like. In a specific embodiment, synthetic environment generation platform 100 is configured to exchange data via a link 140, which can convey communications signals through, for example, any of a number of networks (not shown), including the Internet. In one embodiment, link 140 is configured to transmit and/or receive data at least from about 5 Kbs to about 10 Kbs, or higher. As such, link 140 can support 5 Kbs upstream and 5 Kbs downstream, especially at substantially the same time. In other embodiments, link 140 is a relatively high bandwidth link that can be implemented as a broadband connection, such as using digital subscriber line (“DSL”) technologies, cable technologies, satellite technologies, and the like. Also, link 140 can be a wireless link. In one embodiment, high bandwidth link 140 can transmit and/or receive data at rates faster than 10 Kbs, and, as such, link 140 can implement data transfer rates higher than 10 Kbs. Further, network 115 is configured to transport messages and/or packets at a rate of at least 1 to 16 gigabits per second, or faster. In one embodiment, network 115 is a 10 gigabit Ethernet (“10 GbE”) network.

FIG. 1B is an illustration of game management servers generating, in whole or in part, a synthetic environment in connection with a process space, according to at least one embodiment of the invention. Synthetic environment generation platform 160 is configured to generate a synthetic environment 162 for clients 150 a and 150 b. In this example, synthetic environment 162 includes four regions: region one (“R1”) 163, region two (“R2”) 165, region three (“R3”) 167, and region four (“R4”) 169. Next, consider that participant 170 and participant 172 are respectively associated with clients 150 a and 150 b. Synthetic environment generation platform 160 includes game management processes 120 implemented by game (“mgmt”) management servers 122 a to 122 d. Synthetic environment generation platform 160 also includes a quasi aggregated process space 161 with which synthetic environment 162 can be generated.

According to various embodiments of the invention, quasi aggregated process space 161 is configured to operate as a common process space in some instances and as a collection of separate processes during other instances. In particular, quasi aggregated process space 161 is configured to function as a common process space for a first subset of game data, and is configured to function as separate process spaces for a second subset of data. For example, transaction server 190 is configured to implement quasi aggregated process space 161 as a common process space for non-geometry-related data and transaction-related data, for example, whereas game management servers 122 are configured to implement quasi aggregated process space 161 as separate process spaces for geometry-related data, as an example. In at least one embodiment, synthetic environment generation platform 160 includes a transaction server 190 to implement, in whole or in part, quasi aggregated process space 161. In particular, transaction server 190 has a common process space with which to process both the first subset of data 192 for participant 170 c and the first subset of data 194 for participant 172. Examples of the first subsets of data 192 and 194 include data representing items that the participants wish to trade. The second subsets of data for participants 170 c and 172, for example, can relate to geometry data that, for example, game management servers 122 b and 122 d process.

In operation, when participant 170 logs in, synthetic environment generation platform 160 assigns that participant to game management servers 122 b. By contrast, when participant 172 logs in, synthetic environment generation platform 160 assigns participant 172 to game management servers 122 d. Participant 170 and 172 remain associated with game management servers 122 b and 122 d, respectively, during the session. Next, consider that both wish to engage in an activity at region two 165, as do many other participants that are not shown. Participant 170 a enters synthetic environment 162 at region one 163, and then moves to region two 165 as participant 170 b. As both regions one 163 and two 165 relate to a quasi aggregated process space 161, computational resources that otherwise would be required to manage cross-partition interactions are not needed when, for example, quasi aggregated process space 161 is accessed as a common process space. Participant 170 c can further move to region three 167, and then to region four 169 as participant 170 d. Note that as more participants enter region two 165, the increased number does not correspondingly bog down a server. This is because, according to various embodiments of the invention, game-related processes that generate synthetic environment 162 are not linked to geographic locations. In this example, no one game management server 122 bears the full burden, which can be amortized across game management processes 120 as a whole. Thus, hoards of participants can gather at one region without significantly overwhelming the performance of a single game management server 122.

FIG. 2 is a diagram showing an example of a messaging system in accordance with at least one embodiment of the invention. FIG. 2 shows a synthetic environment generation platform 200 implementing at least a portion of a messaging system 250 configured to couple together, via a network 230, a database process 201, a server process 206, and a client process 240, all of which are nodes. Network 230 can be a computer network or any other type of communications network. Database process 201 includes a database (“d/B”) 202 and a database management system (“DBMS”) 204, which controls the organization, storage and retrieval of data in a database 202. In operation, messaging system 250 is configured to propagate messages, such as messages 220 a and 220 b, that include a universal data structure 260 for integrating data into a node (or a node process), such as server process 206. In particular, messaging system 250 is configured to exchange data among database process 201, a server process 206, and a client process 240 in a data arrangement that is useable by each of the processes. In one or more embodiments, the data arrangement associated with messages 220 a and 220 b is directly useable by each of the processes. For example, server process 206 can use data arranged in accordance with a universal data structure (“UDS”) 260 a used by message 220 a. As such, database process 201, a server process 206, and a client process 240 need not require a conversion from a data structure associated with messages 220 a and 220 b into a different (or specialized) form that otherwise might be required by a specific node. Thus, executable code is absent that otherwise might be required to provide for such conversion.

A shown in FIG. 2, messaging system 250 can include a number of universal message interfaces, such as universal message interface 210 a, universal message interface 210 b, and universal message interface 210 c, each of which can be configured to generate messages 220 a and 220 b for transmission throughout the synthetic environment generation platform and with client processes 240. Universal message interfaces 210 a, 210 b, and 210 c can each be configured to receive messages 220 a and 220 b for integrating their data into a node process. Further, when universal data structures 260 are developed, recompiling executable code is not required that otherwise would be to convert one type of data structure into a different data structure. As used herein, the term “universal data structure,” at least in one embodiment, refers to a representation of data that is universally useable by the nodes, as well as messages 220 a and 220 b, that do not require a conversion into some different (or specialized) data structure.

In various embodiments, universal message interfaces 210 a, 210 b, and 210 c of FIG. 2 can be the same, or, alternatively, can differ to accommodate the node in which they relate. Universal message interfaces 210 a, 210 b, and 210 c can be implemented internal to nodes, or, they can be disposed anywhere within a synthetic environment generation platform. In at least one embodiment, universal message interfaces 210 a, 210 b, and 210 c each can be configured to broadcast messages, such as message 220 a, out to any or all other nodes. As such, universal message interfaces 210 a, 210 b, and 210 c each can be configured to detect whether each of the messages is intended for the node to which a universal message interface relates. In another embodiment, universal message interfaces 210 a, 210 b, and 210 c each can be configured to transmit messages targeted to a destination. In one embodiment, messages between a client and the synthetic environment generation platform, such as message 220 b, can be implemented in one or more User Datagram Protocol (“UDP”) or Internet Protocol (“IP”) packets. In one embodiment, messages among server processes 206 and database processes 201 can be implemented in one or more Transmission Control Protocol (“TCP”) packets. In one embodiment, network 230 supports intra-platform communications for synthetic environment generation platform 200. In at least one embodiment, client process 240 is coupled via network 232 to synthetic environment generation platform 200. Network 232, in at least one embodiment, includes the Internet or any other communications network. In some instances, client process 240 exchanges messages with a database process 201 and/or a server process 206 via an intermediary process (not shown). An example of such an intermediary process is shown as user server of FIG. 12.

In one embodiment, universal data structure 260 is of a class of an object-oriented programming language, such as C++ or any other programming language. In another embodiment, all types of universal data structures 260 can relate to a single class. Universal message interfaces 210 a, 210 b, and 210 c can determine an instance management schema configured to enable a node to implement (e.g., directly implement) data in universal data structure 260. In one embodiment, a node can include a reference to a schema that directs the node on how to implement universal data structure 260. In another embodiment, universal message 220 a includes the reference. In some embodiments, universal message interfaces 210 a, 210 b, and 210 c each can be configured to format the universal data structure in a platform-independent format, which can be used independent of processor and/or operating system. One example of a platform-independent format is a format defined by, for example, an extensible markup language, such as XML. XML is maintained by the World Wide Web Consortium (“W3C”).

FIG. 3 depicts a system for generating synthetic environments that implement universal messaging interfaces in accordance with at least one embodiment of the invention. In this example, a synthetic environment generation platform 300 includes universal message interfaces (“UMI”) 302, 304, and 306 that are configured to transmit and/or receive universal data structure-based messages. As shown, universal message interfaces 302 a, 302 b, and 302 c are disposed at or near game processes 102 a, 102 b, and 102 c, respectively. Each of universal message interfaces 302 a, 302 b, and 302 c is associated with a game subprocess server 104. In some cases, universal message interfaces 302 a, 302 b, and 302 c each can have equivalent structure and/or functionality, and, in other cases, universal message interfaces 302 a, 302 b, and 302 c can have different structures and/or functionalities. For example, a physics server might require a different universal message interface than, for example, an artificial intelligence server. FIG. 3 also shows that synthetic environment generation platform 300 includes universal message interfaces 304 a, 304 b, and 304 c being disposed at or near databases 112 a, 112 b, and 112 c, respectively, and universal message interfaces 306 a, 306 b, 306 c, and 306 n being disposed at or near game management servers 122 a, 122 b, 122 c, and 122 n, respectively. Universal message interfaces 308 a and 308 b are implemented in relation to clients 150 a and 150 b. Note that 304 a, 304 b, 304 c, 306 a, 306 b, 306 c, 306 n, 308 a, and 308 b can have either equivalent or different structures and/or functionalities with respect to each other. Note, too, that similarly-named elements of FIG. 3 can have, in some cases, an equivalent structure and/or functionality as those elements set forth in FIG. 2.

FIG. 4A depicts a method for introducing dynamic content into a synthetic environment, according to at least one embodiment of the invention. Diagram 401 depicts the development of, for example, a massively multiplayer online (“MMO”) game using a synthetic environment generation platform, according to one embodiment. During code development and compilation stage 431, game developers can generate and compile source code to form object code 421 as executable code. In developing the source code, socket code 423 can be generated and compiled. Socket code 423 includes executable instructions and/or inputs configured to access data from plug data 425. As such, plug data 425 can be developed in coordination with both socket code 423 and object code 421 as part of a quality assurance (“QA”) process. After quality assurance metrics are met, both object code 421 (including socket code 423), and plug data 425 can be released for on-line gaming. Subsequent to code development and compilation stage 433, content developers can implement a synthetic environment generation platform to create other plug data 427 during a post-code compilation stage 433. During stage 433, plug data 427 can be created for use with socket code 423 without revising object code 421. For example, content developers can substitute an Aegis Cruiser as plug data 427 for a kayak that was formed by plug data 425, without modifying executable code. By foregoing a recompilation of the object code, developers can more quickly deliver new dynamic content into a synthetic environment implementing socket code 423. Further, future plug data 470 can be created without affecting the object code, thereby facilitating relatively rapid content development. As used herein, the term “dynamic content,” at least in one embodiment, refers to content data that can be introduced into a synthetic environment as computer-generated visual and/or sound content, whereby the content data can be created independent to the modification of executable code with which the content data interacts. As such, content data can be developed without affecting object code.

FIG. 4B depicts a synthetic environment generation platform configured to introduce dynamic content into a synthetic environment, according to at least one embodiment of the invention. In this example, system 400 includes a synthetic environment generation platform 450 that is configured to generate a synthetic environment 420 with which participants interact, and into which dynamic content 422 is introduced. System 400 includes data repositories 402, 430 and 460. In particular, data repository 402 is configured to store plug objects 410 a and 410 b that include content data for introducing a kayak and an Aegis cruiser, respectively, as dynamic content 422. Plug objects 410 a and 410 b can implement data arrangements similar to, or the same as, the universal data structures of the various embodiments. Plug objects 410 a and 410 b can also include data representing location, positioning, speed, and a path 424 along which a boat can sail. Data repository 430 is configured to store object code 434 for running, for example, a massively multiplayer online game. Data repository 430 is also configured to store socket code 432, which can form a portion of object code 434. Socket code 423 includes executable instructions and/or inputs configured to access data from plug data 425 (of FIG. 4A) for use by object code 434 to effectuate generation of dynamic content 422. Data repository 460 is configured to store world data 462 to form synthetic environment 420. World data 462 and socket code 432 can share a relationship 464 for defining the locations at which socket code 423 will introduce dynamic content 422.

Synthetic environment generation platform 450 includes an event server 452, which is configured to introduce dynamic content 422 into at least a portion of synthetic environment 420. The dynamic content 422 can be introduced substantially coincident to the execution of object code instructions to generate synthetic environment 420. As such, synthetic environment generation platform 450 can be configured to initialize a plug insertion process 440, during which one of plug objects 410 a and 410 b is inserted into socket code 432 to instantiate dynamic content 422. In a specific embodiment, event server 452 is configured to introduce dynamic content 422 without modifying object code 434. In one embodiment, plug objects 410 a and 410 b belong to a system of universal objects that includes at least one universal data structure. Further, plug objects 410 a and 410 b, and the system of universal objects, obviate recompilation of object code instructions 434 to introduce dynamic content 422. By implementing plug objects 410 and socket code 432, at least one game management server can be configured to generate dynamic content 422 without rebooting, such as after implementing modified object code.

FIG. 5 is an illustration of a process space for use in generating synthetic environments in accordance with at least one embodiment of the invention. Here, a synthetic environment generation platform 500 is configured to generate a synthetic environment for clients 550 a and 550 b. Synthetic environment generation platform 500 includes game management processes 520 implemented by game management (“mgmt”) servers 522 a to 522 n. Synthetic environment generation platform 500 also includes quasi aggregated process space 502 in which transactions, such as transaction 504, can be implemented as an atomic transaction. As such, either the all parts of a transaction are performed or none of them is. To illustrate, consider an example in which a first participant (“participant 1”) 506 is associated with client 550 a, and a second participant (“participant 2”) 510 is associated with client 550 b. First participant 506 and second participant 510 respectively possess an item (“Item A”) 508 and an item (“Item B”) 512. Next, consider that the participants 506 and 510 arrange to exchange items 508 and 512, but have yet to confirm their wishes. Once both participants 506 and 510 agree to the exchange, the transaction is finalized. During transactions such as this, quasi aggregated process space 502 is configured to behave a common process space, thereby making transaction 504 less vulnerable to manipulation. In one embodiment, a transaction server (not shown) operates to either interact with or provide quasi aggregated process space 502. According to one embodiment, quasi aggregated process space 502 emulates a common process space, and as such, enables participants to transfer readily among different synthetic environments created by different synthetic environment generation platforms 500. As used herein, the term “transaction,” at least in one embodiment, refers to a set of tasks constituting an activity that involves one or more participants interacting with a synthetic environment.

FIG. 6 is a diagram showing an example of a portion of a messaging system implementing a compressed universal message, according to at least one embodiment of the invention. Here, message system portion 600 includes a server process 606 and a client process 650, both of which are coupled via a network 630 for exchanging messages, among other things. In this example, message system portion 600 can transport a subset of data associated with a server-side (or a client-side) universal data structure 660, such as in response to client process 650 indicating a modification to the synthetic environment. Server process 606 and client process 650 respectively include universal message interface 610 a and universal message interface 610 b. Server process 606 can use data arranged in accordance with a universal data structure (“UDS”) 660 to, in whole or in part, generate a synthetic environment in response to game data modifications transmitted from client process 650. An example of modified game data is the game data generated by client process 650 that indicates movement by an avatar. In at least one embodiment, server process 606 and/or client process 650 can exchange messages as a compressed universal message 620. As both server process 606 and client process 650 can implement universal data structure 660 with which to exchange data, a reduced amount of data can be exchanged in compressed universal message 620. In particular, only modified game data 624 associated with universal data structure 622 need be transported in a universal message. In one embodiment, compressed universal message 620 also includes a key 628 specifying which attribute modified game data 624 relates. With this information, server process 606 can modify the synthetic environment.

FIG. 7 depicts a system for generating synthetic environments that implement a master scaling server, according to at least one embodiment of the invention. Synthetic environment generation platform 700 includes an inter-process messaging network 750 and a master scaling server 752, both of which are configured to scale game subprocess capabilities to satisfy variations in demand for game subprocesses, such as physics processes and artificial intelligence processes. Synthetic environment generation platform 700 also includes various game subprocesses 702, database processes 710, and game management processes 720. In operation, master scaling server 752 is configured to add or remove game subprocess servers as appropriate. For example, if more physics processing is needed, master scaling server 752 can add additional physics servers. But if less artificial intelligence is needed, master scaling server 752 can take artificial intelligence servers off-line.

Master scaling server 752 is configured to monitor a list of servers, which also includes information about the type of server (e.g., whether a server is a physics server, artificial intelligence server, etc.), the synthetic environment to which game subprocess server 702 belongs, and the like. Master scaling server 752 is also configured to monitor request messages for additional game subprocesses via inter-process messaging network 750 from, for example, one or more game management servers requiring additional services or capacity. In response, master scaling server 752 can coordinate establishment of connections among a newly-added game subprocess server, such as any of game subprocess servers 704 a, 704 b, and 704 c, and a requesting server, such as a game management server.

In one embodiment, a scalable game subprocess server is configured, when brought on-line, to communicate its identity and other related information to master scaling server 752. The other related information can include a server type, an associated synthetic environment to which it belongs, etc. In response, master scaling server 752 dynamically allocates the scalable game subprocess server to, for example, a game management server requiring such a server type. In particular, master scaling server 752 sends a command and connection information (e.g., host and port information) to the scalable game subprocess server to connect to the requesting game management server. In some cases, master scaling server 752 communicates connection information (e.g., host and port information) to the requesting game management server to receive a connection from the scalable game subprocess server. In at least one embodiment, master scaling server 752 can be configured to monitor the loading of game management servers, and, automatically add or remove game subprocess servers. In one embodiment, an inter-process messaging network 750 is coextensive with or is the same as a universal messaging system implemented over network 715.

FIG. 8 is a diagram showing an example of a master scaling server adding scalable game subprocess servers, according to at least one embodiment of the invention. In particular, diagram 800 depicts game subprocess servers 804 providing a game subprocess 802 that is used by a game management server (not shown). Also shown, master scaling server 852 is adding scalable physics servers 810 to boost physics processing capabilities. In one embodiment, scalable physics servers 810 and game subprocess servers 804 are each homogeneous hardware platforms. With homogeneous hardware platforms, master scaling server 852 can increase the flexibility for scaling up and down as necessary.

FIG. 9 is an illustration of a synthetic environment generation platform implementing specific types of game subprocess servers, according to at least one embodiment of the invention. Synthetic environment generation platform 900 includes game subprocesses 901, a game database 910 configured to store game data, and game management processes 920, which include game management servers 922 a to 922 n. In this example, game subprocesses 901 include the following specific types of game subprocess servers: a physics server 902 a, an artificial intelligence (“AI”) server 902 b, and a transaction server 902 c. By implementing these game subprocesses in separate servers, synthetic environment generation platform 900 is less susceptible to problems associated with a game subprocess. Further, certain game subprocesses can be scaled appropriately to meet a demand independent from other game subprocess needs.

Physics server 902 a represents one or more physics servers configured to process movement and collision detection activity for the synthetic environment. In various embodiments, physics server 902 a can also perform any of the following: visibility determinations, instancing, movement validation and/or path segmenting for artificially intelligent NPCs. In making visibility determinations, physics server 902 a calculates whether objects and/or other participants in a synthetic world are visible to a participant. An entity is visible to a participant when that entity is within a visibility range of the participant, where physics server 902 a determines whether the entity is in the visibility range. FIG. 11 illustrates an alternate technique for determining visibility, according to an embodiment of the invention. Referring back to FIG. 9, physics server 902 a also can be configured to provide “instancing,” whereby a collection of participants (and associated physics processing) perform activities within a portion of the synthetic environment, such as in a virtual house, or in an area at which they will band together to fight an NPC, such as a boss monster.

Movement validation is the act of validating the movement of a participant in the context of the synthetic environment. Physics server 902 a can be configured to validate movement against the virtual terrain and any entities (i.e., other characters and/or objects) that are in the path of the desired movement. Based on the rate at which the participant's avatar moves relative to the virtual terrain, the location of the participant can be modified to reflect its location in the synthetic environment. Physics server 902 a can run a simulation to validate that the location is correct before sending modified game data to the clients. Physics server 902 a can also be configured to validate movement of a participant to ensure that participant is permitted to either engage in certain activities or move within certain areas of the synthetic environment. In one embodiment, physics server 902 a validates a subset of participants per unit time, and cycles through different subsets over time. Any participant that is not authorized to move about or at certain areas of a synthetic environment, then that participant can be tagged as being suspected of performing an exploit. Further, physics server 902 a can provide path segments to artificial intelligence (“AI”) server 902 b so that NPCs can avoid objects that other would block movement of an NPC, due to the terrain and/or static objects. In various embodiments, one or more of the above-discussed physics processes can be implemented as separate processes in separate servers.

Artificial intelligence (“AI”) server 902 b represents one or more artificial intelligence servers configured to provide computer-implemented non-player characters (“NPCs”) and the like with artificial intelligence to determine the behavior of NPCs. Additional artificial intelligence servers 902 b can be added to support the synthetic environment during increased demands for artificial intelligence. For example, if an event requires a large number of NPCs, then additional artificial intelligence servers 902 b can be added. In one embodiment, a participant can assume control of an NPC to “play the monster.”

Transaction server 902 c represents one or more transactions servers configured to process, among other things, run-time participant game data, regardless of the location of the participant. As such, transaction server 902 c includes a cache 903 to facilitate character (i.e., participant) movement between, for example, a persistent world (i.e., a synthetic environment) and an instance (i.e., a portion of the synthetic environment, such as in virtual building). Using cache 903 avoids having to reload game data from the database as the participant moves between synthetic environments and portions thereof. In some embodiments, representations of game data are marked as read-only in processes other than transaction server 902 c to, for example, avoid manipulation of transactions. Further, transaction server 902 c facilitates atomic transactions within a quasi aggregated process space. While transaction server 902 c performs transactions, game management servers 922 a to 922 n can be configured to validate participants to confirm their identities prior to transaction server 902 c modifying the data in response to a transaction.

FIG. 10 is a diagram showing an implementation of physics processes, according to at least one embodiment of the invention. Diagram 1000 shows visibility processes and instancing processes being off-loaded from physics server 1002 into separate visibility server 1004 and instance server 1006, respectively. Visibility server 1004 is configured to determine whether objects and/or other participants in a synthetic world are visible to a participant. Instance server 1006 is configured to providing “instancing,” whereby a collection of participants and associated physics processing for performing a group or localized activity within a portion of the synthetic environment. With visibility processes and instancing processes being separate from the physics processes for the synthetic environment, physics server 1002 is less burdened. Further, visibility server 1004 and instance server 1006 are less susceptible to problems relating to physics server 1002.

FIG. 11 is a diagram showing a technique for determining visibility, according to at least one embodiment of the invention. Diagram 1100 illustrates an example of a technique for determining the visibility for a participant 1104. In one case, a visibility server first defines a visibility range 1102 for defining participant 1104. As such, participant can see objects at a distance 1106. In at least one embodiment, objects, NPCs, and other players each are associated with a “can-be-seen” range. Larger objects, such as a mountain 1114, can have a larger “can-be-seen” range 1112, than smaller objects, such as a mouse 1124, which has a “can-be-seen” range 1122. In one embodiment, a visibility server is configured to implement a sphere intersection test in which an object becomes visible to participant when a “can-be-seen” range, such as “can-be-seen” range 1112 for mountain 1114, intersects with visibility range 1102. A “can-be-seen” range can be represented as a circle (i.e., 2-D) or a sphere (i.e., 3-D). Note that in a specific embodiment, participant 1104 has two ranges: (1.) a participant visibility range defined by sphere 1102, and (2.) a “can-be-seen” range 1160 at which other entities can see participant 1104 if the entity or its visibility range intersects “can-be-seen” range 1160. Next, consider that a giant 1150 has a visibility range 1152 at a distance 1154 from the giant, and has a “can-be-seen” range 1153 at a distance of 1155 from the giant. Further, participant 1104 has a “can-be-seen” range 1160 at a distance of 1158 from participant 1104. So when giant 1150 approaches participant 1104, and its visibility range 1152 intersects “can-be-seen” range 1160, then giant 1150 can see participant 1104. But when visibility range 1152 is within a visibility gap 1160, the participant cannot see giant 1154. Note that once visibility range 1152 intersects visibility range 1102, then participant 1104 can see giant 1150. In view of the foregoing, diagram 1100 illustrates an example for a technique to determine visibility that reduces unnatural visual effects (e.g., entities appear to “pop up” when they cross visibility range 1102) that can occur when only a visibility ranged is used to determine visibility. While not shown, mouse 1124 also can have a visibility range. In various embodiments, non-player characters (“NPCs”) and participants each can have a visibility range and a “can-be-seen” range.

FIG. 12 is an illustration of a synthetic environment generation platform implementing additional types of game subprocess servers, according to at least one embodiment of the invention. Synthetic environment generation platform 1200 includes game subprocesses 1202, a game database 1212 a configured to store game data, an audit database 1212 b configured to store audit data (i.e., a record of all or most interactions by each participant) and statistical data, and game management processes 1220, which include game management servers 1222 a to 1222 n. In addition, synthetic environment generation platform 1200 includes a user server 1270, a patch server 1272 and a stats/audit server 1274.

User server 1270 can be configured to route messages between any of game management servers 1222 a to 1222 n and client 1250. However, once a participant logs in to interact with the synthetic environment, user server 1270 will assign participant and its client 1250 to one of game management servers 1222 a to 1222 n. Thereafter, user server 1270 can relay messages to and from one of game management servers 1222 and the participant. During the session, the participant can retain a relationship with the same game management server. User server 1270 can also be configured to connect clients 1250 in a manner that distributes client connections evenly across game management servers 1222 a to 1222 n, thereby effecting load balancing. In some cases, user server 1270 can also be configured to authenticate participants upon signing on. In at least one instance, user server 1270 can selectively encrypt data exchanged between game management servers 1222 a to 1222 n and client 1250. In one embodiment, user server 1270 foregoes encrypting movement-related messages, which are a predominant amount of messages. As such, the delays associated with encryption are reduced. Patch server 1272 can be configured to incrementally transmit patches to client 1250, such as on a file-by-file basis. In at least one embodiment, patch server 1272 is configured to trickle patches at an opportune time, such as at login, as well as during game play (i.e., during interactions by a participant with a synthetic environment). Stats/audit server 1274 is configured to collect and use statistics for participant use and/or for triggering events in connection with an event server.

FIG. 13 is a diagram showing a technique for enabling game play during patching, according to at least one embodiment of the invention. Diagram 1300 illustrates regions added as new “worlds,” “continents” or synthetic environments. The progression of synthetic environment expansion is shown by arrow 1330. Consider that region (“1”) 1302 was implemented with an originally downloaded game. Next, consider that region (“2”) 1312 represents an expanded synthetic environment for which a participant downloaded a patch. Lastly, consider that the participant has yet to implement the next patch for region (“3”) 1322, but wishes to enter region 1322 from region 1302. As the participant travels from region 1302 to region 1312, the participant will observe tree 1304 and tree 1314. But as participant passes over delineation 1316, the participant will be in a local that has yet to be completed. As such, synthetic environment generation platform will display a proxy asset (i.e., a substitute object) 1324 if the patching data to render a tree is yet to be completed. As such, the participant need not be prohibited from entering the new region 1322, but might experience fill-in objects until the patching process is completed.

FIG. 14 is an illustration of a synthetic environment generation platform implementing an event server and an event editor, according to at least one embodiment of the invention. Synthetic environment generation platform 1400 includes game subprocesses 1401, a game database 1410 configured to store game data, and game management processes 1420, which include game management servers 1422 a to 1422 n. Synthetic environment generation platform 1400 also includes an event server 1430 and an event editor 1480. Event server 1430 is configured to control the introduction of dynamic content into synthetic environments as a function, for example, of player activity, such as triggering a predetermined trigger or condition, and/or pre-determined scheduling. For example, if a number of participants congregating at a specific location surpass a trigger point, then event server 1430 can trigger introduction of dynamic content. In some embodiments, event server 1430 can modify the types of ships or creatures that are spawned. Event server 1430 is configured to access plug objects from event library database 1412 to generate dynamic content. In one embodiment, event server 1430 is configured to generate data to drive an Event Server Guide 1490 that displays programmed events for participants to preview and join those events. Event editor 1480 is configured to aggregate plug objects in association with a number of sockets to introduce varying amount of dynamic content, whereby the collection of plug objects can introduce creatures, trees, structures, and the like into a synthetic environment.

FIG. 15 depicts a flow for creating events for introducing various degrees of dynamic content, in accordance with at least one embodiment of the invention. Flow 1500 is an example of a method to create an event using plug objects, which include universal data structures stored in an event library. At 1502, an event is defined and requirements are indicated. At 1504, game designers create a new event by, for example, using pre-made plug objects, until the new event is established at 1506. At 1508, the event is tested to confirm that the new event meets quality assurance (“QA”) specifications. If the event fails at 1510, then flow 1500 returns 1502 to redefine or correct the event definition and/or implementation. If the event is successful, then it is stored at 1512 in an event library. At 1522, the event is scheduled for introduction into a synthetic environment. At 1524, the event server 1526 is configured to trigger event at a predetermined time. At the scheduled time, event server 1526 fetches the data related to the event from event library 1512 and causes synthetic environment generation platform 1528 to implement the event (e.g., by generating dynamic content). Then, the dynamic content is released to client at 1530 for use in the computer-generated world.

In one embodiment, flow 1500 provides for the introduction of dynamic content into synthetic environments by way of a patch server process, as implemented in patch server 1580. In this example, patch server 1580 is configured to detect when data representing an event is deposited into the event library at 1512. Further, patch server 1580 is configured to push, or “trickle down,” data required by the event down to the client as small files or pieces of data 1582. Accordingly, patch server 1580 can push data down at off-peak usage times and can avoid exceeding allotted bandwidth capacities that can otherwise occur when large downloads, such as 250 MB, happen during peak usage periods, which is costly. In another embodiment, patch server 1580 determines the amount of data to be pushed and the remaining time to the event, and, therefore calculates an average amount data that needs to be pushed per unit time. As such, patch server 1580 can vary the amounts of data in the small files 1582 for optimal transport. In a specific embodiment, patch server 1580 can be configured to access peak threshold monitoring data in database 1584 to determine when to vary the sizes of small files 1582 so as to avoid large amounts of data being pushed at peak usage times.

FIG. 16 is a diagram showing a specific implementation of a universal data structure in accordance with at least one embodiment of the invention. Universal data structure 1602 is shown as a property class object identified by identifier 1604 (i.e., “Property Class xxxxxx”). The property class object includes an arrangement of data that includes attributes 1606, each of which can correspond to a property of Property Class xxxxxx, such as described below in relation to a universal data structure specification file 1622 of FIG. 16. Further, an attribute 1606 can correspond to a property value (e.g., string, integer, etc.), such as described in relation to universal data structure 1702 of FIG. 17. In various embodiments, universal data structure 1602 can include nested universal data structures (or references thereto). To illustrate, consider that Property Class xxxxxx can define the properties of a ship, such as described in FIG. 20. Universal data structure 1602 then can include a nested universal data structure that defines the properties of “positioning” that the ship possesses.

FIG. 16 also includes a diagram showing an example of a universal data structure specification file in accordance with at least one embodiment of the invention. Universal data structure specification file 1622 provides for an instance management schema, which uses nodes in a synthetic environment generation platform to access data embodied in a universal data structure. Universal data structure specification file 1622 may include metadata for each property class object, which may be configured to provide corresponding property values for assigned attributes. In some embodiments, a property class object or PropertyClass object (hereafter “property class object”) may be an object having data or information that is used to determine how to render, generate, or instantiate various types of objects, information, and other parameters within a synthetic environment. Further, property class objects may be configured to provide reduced message data that, when used with, for example, high-speed or large capacity network connections, enable rapid or fast game play, synthetic environment generation, and the like. For example, a property class object may include all or a portion of data that is used to instantiate an object. A synthetic environment generation platform (or nodes therein) may implement the metadata for creating, displaying and/or implementing values of game data. Further, universal data structure specification file 1622 may be referenced by identifier 1624 (i.e., “Property Class Specification yyyyy”), and can include a reference 1626 to an instance management schema at, for example, location “instance.mgmt.schema.” In some embodiments, the instance management schema is a data model describing the use of a node to access data in property class objects. Further, universal data structure specification file 1622 can include the property values (or references thereto) for property class objects 1630.

FIG. 17 is a diagram depicting elements of a property class system, according to at least one embodiment of the invention. In some embodiments, property class 1704 may be implemented as universal data structure 1702, and can have one or more properties (“Property”) 1706. Here, property class 1704 is configured to be a container of specific property pointers to corresponding properties values. Further, the one or more properties 1706 can include property values, such as a string (“PropertyString”) 1708 a, an integer (“PropertyInt”) 1708 b, a large integer (“PropertyBigInt”) 1708 c, and others.

Universal data structure specification file 1722 is shown as including a property class specification 1724. As such, instances of a common type of property class 1704 may relate to a property class specification 1724. For example, property class 1704 named “Player” may have, for example, a relationship to property class specification 1724, which specifies properties and property values. Further, property class specification 1724 can include a vector of pointers to one or more property specifications (“PropertySpec”) 1726, each of which may contain metadata associated with properties 1706. A property class manager (“PropertyClassManager”) 1742 can include a map (e.g., a look-up table) for determining a property class name and a property class specification as a key and value pair. During run-time or execution, a synthetic environment generation platform (or nodes therein) can use property class manager 1742 to manage the implementation of data structures and the game data from the property class system.

FIG. 18 depicts a flow for creating a universal message in accordance with at least one embodiment of the invention. Flow 1800 shows a universal data structure editor 1802 being configured to edit or create one or more property class object files, such as XML-based object data files 1803. Universal data structure editor 1802 can be, for example, an editor that provides context-friendly interface elements, such as drop down menus and data range validation based on the associated property class specs. Further, universal data structure editor 1802 uses the XML Reader 1806 and XML Writer 1805 to serialize the data to and from the source, which can be one or more of XML-based object data files 1803. In various embodiments, universal data structure editor 1802 can be configured to edit data formatted in accordance with extensible markup language (i.e., XML), hypertext markup language (i.e., HTML), and any other markup or formatting languages. Universal data structure editor 1802, in some instances, may be replaced with XML-based editor 1807 because the property class representation is in an XML-compliant format. XML-based editor 1807 may be any one of a number of commercially available tools, such as XMLSpy produced by Altova, Inc. of Beverly, Mass.

A property class data file 1803 is brought into the runtime environment using the serialization or XML Reader 1806 facility of the property system. This takes the XML-based property class data from a file 1803 and creates an “in-memory” C++ property class object representation 1809. Any modifications may be reflected back to the original source using the XML Writer 1805 facility.

To facilitate speed of serialization and obfuscation of data versus an XML representation, the property class object 1809 can be serialized to a disk-based binary format 1810 using the Binary Reader 1808 and Binary Writer 1801 mechanisms. This enables developers to edit in a human-readable format (i.e., XML) using convenient tools, and convert the XML into a binary format, when speed of execution and obfuscation are important.

Should any instance of a C++ object 1809 need to be transmitted over a network, the property class object is “packed” or “packetized” for transport in transmitter 1850. The packetize process at 1811 will use the services of the Binary Writer 1801 to create the packet and will transmit the packet at 1812 via link 1842. While receiver 1852 receives the packet and will use the services of the Binary Reader 1801 to unpack the data into an instance of the in memory C++ property class object representation 1809. Note that either transmitter 1850 or receiver 1852, or both, can be implement in universal message interfaces, according to various embodiments of the invention.

FIG. 19 illustrates elements of a property class system for creating a universal message in accordance with at least one embodiment of the invention. Diagram 1900 depicts a universal message creation process 1940 that uses the following property class system elements: property class objects, such as property class objects 1902, 1904, and 1906, a property class manifest 1910, a property class manager 1920, and a property class specification file 1930. For illustration purposes, consider that universal message creation process 1940 is configured to generate a universal message regarding character data. As such, universal message creation process 1940 uses property class object (“player”) 1906, which includes nested property class objects 1902 and 1904. Nested property class object (“spells”) 1902 includes a data arrangement of data representing, for example, the types and strengths of spells that a player possesses. Nested property class object (“weapon”) 1904 includes a data arrangement of data representing, for example, the kinds of weapons that the player possesses.

In at least one embodiment, property class manifest 1910 is configured to provide a space for listing or assembling information and data that may be used by a property system to instantiate property class objects. For example, property class manifest 1910 may include a list of property class identifiers (“IDs”), specification file (e.g., specification file 1722 (FIG. 17)) names, category tags for each listing to help group property class objects, and others. Further, property class manifest 1910 can describe file names, property class object names, and other resources (or sources of information) for creating a universal message. Property class manager 1920 can include a map of logical and physical resources and data to manage the implementation of data structures of property class objects 1902, 1904, and 1906 and the game data therein. Property class specification file 1930 can include property values or references to property values.

A synthetic environment generation platform and/or its nodes can implement universal message creation process 1940 and the above-described property class system elements to form a universal message (or a universal data structure), which can be used by the nodes of a synthetic environment generation platform, such as that shown in FIGS. 1 and 3, among others. When a node (e.g., a server, client, peer, or other processor) initiates a universal message creation process 1940, a universal data structure may be implemented as part of the universal message. Consider next that process 1950 receives implemented universal message. As such, process 1950 can use data 1952 directly from the message without requiring compilation of its source code.

FIG. 20 illustrates elements of a property class system for creating a plug, according to at least one embodiment of the invention. Diagram 2000 depicts a plug creation process 2040 that uses the following property class system elements: property class objects 2002-2006, a property class manifest 2010, a property class manager 2020, and a property class specification file 2030. For illustration purposes, consider that plug creation process 2040 is configured to generate a plug for rendering the image or game element of a ship (e.g., freighter, tanker, warship (e.g., a Ticonderoga-class, Aegis guided missile cruiser), cruise liner, ocean liner, and others) as dynamic content into a synthetic environment. As such, plug creation process 2040 uses a plug property class object (“ship”) 2006, which includes nested plug property class objects 2002, 2004 and 2005. Nested property class object (“positioning”) 2002 includes a data arrangement of data representing, for example, the positioning and relative motion that the ship will possess. Nested property class object (“speed”) 2004 includes a data arrangement of data representing, for example, the speed at which the ship steams (i.e., moves). Nested property class object (“appear as ship”) 2005 includes a data arrangement of data that describes, for example, the appearance of a ship that looks like a desired ship shape. In at least one embodiment, property class manifest 2010, property class manager 2020, and property class specification file 2030 can have similar functions and/or structures as described in FIG. 19. In some embodiments, a plug can refer to representations that specify, for example, data, assets, procedural action list and conditional triggers, among other things. An example of a data representation is property class object 2004, which includes data specifying the speed of a ship. An example of an asset representation is plug property class object 2006, which includes data specifying a ship as an asset. An example of a representation for a procedural action list includes data that specifies actions that the plug object should perform. For example, procedural action list data can specify that a ship will: (1.) turn toward a harbor, (2.) keep sailing, and (3.) stop at a dock. An example of a conditional trigger representation includes data specifying that X should happen once the conditional trigger fires at event Y. For example, conditional trigger data can specify that the ship should blow up once it arrives at the dock.

A synthetic environment generation platform and/or its nodes can implement plug creation process 2040 and the above-described property class system elements to form plug data 2052. Consider next that process 2050 is the recipient of plug data 2052. In particular, plug data 2052 includes one or more universal data structures that can provide game data to socket code 2054 of process 2050. As such, process 2050 can use plug data 2052 to introduce dynamic content into a synthetic environment without requiring further or additional compilation of the source code for either process 2050 or socket code 2054. In one embodiment, plug data 2052 can be stored as ship plug data 2061 in a database (“d/B”) 2060. A user can use event editor 2064 to collaborate with an event server 2062 to create ship plug data 2061. Further, the user can use event editor 2064 to schedule the date and time at which ship plug data 2061 is plugged into socket code 2054 for generating dynamic content, for example, at a scheduled time. In some embodiments, event editor 2064 can be an application built on top of either an XML editor or a property class editor.

FIG. 21 is a diagram showing a portion of a messaging system implementing a compressed universal message, according to at least one embodiment of the invention. Here, message system portion 2100 includes a server process 2106 and a client process 2150, both of which are coupled via a network 2130 for exchanging messages, among other things. In this embodiment, message system portion 2100 can transport a message as a universal data structure, including a subset of data associated with a server-side (or a client-side) property class object (“<pco>”) 2160. An example of such a message is a response from client process 2150 indicating a modification to the synthetic environment. Server process 2106 and client process 2150 respectively include universal message interface 2110 a and universal message interface 2110 b. Server process 2106 can use data arranged in accordance with property class object 2160 to, in whole or in part, generate a synthetic environment in response to game data modifications transmitted from client process 2150. An example of modified game data is the data generated by client process 2150 to cause movement for an avatar in the synthetic environment. In at least one embodiment, server process 2106 and/or client process 2150 can exchange messages as a compressed universal message 2120. As both server process 2106 and client process 2150 can implement property class object 2160 with which to exchange data, a reduced amount of data may be exchanged in compressed universal message 2120. In some embodiments, modified game data 2124 associated with property class object 2122 may be transported in a universal message. As an example, consider that modified game data 2124 specifies a modified value for a certain property, which may be identified by an index. As such, compressed universal message 2120 may include index 2128 to identify a related attribute of modified game data 2124. With this information, server process 2106 may be configured or implemented to modify the synthetic environment.

FIG. 22 is an illustration of multiple devices implementing a universal messaging interface to interact with a synthetic environment generation platform, according to at least one embodiment of the invention. Synthetic environment generation platform 2800 includes game subprocesses 2282, database processes 2284, and game management processes 2286, which include game management servers 2288 a to 2288 n. As is shown, a variety of clients 2290 implementing a universal messaging interface (“UMI”) 2292 can interact with synthetic environment generation platform 2200 via a network 2289, such as the Internet In this example, set top box 2290 a, mobile device 2290 b, computing device 2290 c, game console 2290 d, satellite receiver (“RX”) 2290 e, cell phone 2290 g, personal digital assistant (“PDA”) 2290 h, and television 2290 i, among other things, can be configured to implement a universal messaging interface (“UMI”) 2292 as is described herein. In at least one embodiment, any device 2290 f that includes logic (e.g., a processor and memory) can implement universal data structures and/or property classes of the various embodiments to participant in a synthetic environment.

FIG. 23 depicts a system for performing transactions in synthetic environments in accordance with some embodiments of the invention. Synthetic environment generation platform 2360 is configured to implement a quasi-aggregated process space 2390 for a synthetic environment 2362 with which clients 2350 a and 2350 b interact to perform transactions, among other things. In some embodiments, quasi-aggregated process space 2390 can be configured to implement a common process space 2396 and/or one or more separate memory spaces, such as process space (“1”) 2392 and process space (“2”) 2394. As used herein, the term “process space,” at least in one embodiment, can refer to a memory space accessible by a processor (e.g., one or more central processing units (“CPUs”)) to implement an application, or execute instructions and/or maintain data for generating synthetic environment 2362 (or portions thereof) as well as performing interactions therein. A process space can be an address space having any number of addresses. In one example, a process space can be a 64-bit address space. In the example shown, separate process spaces 2392 and 2394 range from address 0×000 . . . 0 to 0×1FF . . . F, and common process space 2396 ranges from address 0×000 . . . 0 to 0×2FF . . . F (e.g., approximately double the amount of addresses of one of separate process spaces 2392 and 2394). But note that separate process spaces 2392 and 2394 and common process space 2396 can have any number of addresses, and need not have the same amount of memory or be any multiple of another. In some examples, a process space can be a virtual memory space. In some embodiments, separate process spaces 2392 and 2394 are composed of read-only memory and cannot be over-written or otherwise modified, whereas common process space 2396 is composed of read/write memory that can facilitate modification of game data associated, for example, with participants 2370 b and 2372 b.

Separate process spaces 2392 and 2394, and common process space 2396 each can be a distinct process space, according to some embodiments. Thus, separate process spaces 2392 and 2394 and common process space 2396 can be implemented in one or more physical memories. In some embodiments, quasi-aggregated process space 2390 can reside in (or in association with) transaction server 2342. In other embodiments, any of process spaces 2392 and 2394 and common process space 2396 can be distributed anywhere in synthetic environment generation platform 2360. In one example, process spaces 2392 and 2394 can reside in (or be associated with) game management server 2322 a and game management server 2322 b, respectively, and common process space 2396 can reside in (or be associated with) transaction server 2342.

Synthetic environment generation platform 2360 includes nodes (and node processes) that are networked or otherwise communicatively coupled together to use quasi-aggregated process space 2390 with synthetic environment 2362. The node processes include game management processes 2320, transaction processes 2340, and database management processes 2380, which include database processes that manage storage and retrieval of data. Game management processes 2320 interact with game subprocesses (not shown) and database management processes 2380 to generate game data representing synthetic environment 2362. For example, game management processes 2320 can include one or more graphics engines (not shown) to render digital imagery based on 3D computer graphics techniques. Further, game management processes 2320 can be configured to manage game data that represents is configured to control interactions between participants 2370 b and 2372 b, as well as with synthetic environment 2362. Such interactions also include interactions with other participants (not shown), non-player characters (“NPCs”) (not shown), or any entity or object associated with synthetic environment 2362. In some embodiments, game management processes 2320 can be implemented using game (“mgmt”) management servers 2322 a and 2322 b (as well as others that are not shown) that collaborate to generate synthetic environment 2362 and participants 2370 b and 2372 b. Thus, game management servers 2322 a and 2322 b each can operate as a game server to provide for multiplayer on-line games (e.g., massively multiplayer online games), or any other interactive simulation application, such as a simulated classroom, a simulated lecture hall, a simulated orchestra hall, a simulated city or organization, a simulated battlefield, etc. In some embodiments, participant 2370 a and participant 2372 a can be associated with clients 2350 a and 2350 b, respectively. In some embodiments, participants 2370 a and 2372 a are users of synthetic environment generation platform 2360 and are associated with data that represents participants 2370 b and 2372 b in the synthetic environment (e.g., the data can be configured to implement participants 2370 b and 2372 b as avatars). As such, participants 2370 b and 2372 b can be perceived as being part of, or interacting with, synthetic environment 2362. In some embodiments, participants 2370 a and 2372 a can be human users or computer-implemented users, or any combination thereof.

Quasi-aggregated process space 2390 can be configured to operate as common process space 2396 in some modes of operation, and as one or more separate process spaces 2392 and 2394 in other modes of operation. In particular, quasi-aggregated process space 2390 can be configured to function as common process space 2396 for a first subset of game data in some modes of operation, whereas quasi-aggregated process space 2390 can be configured to function as one or more of separate process spaces 2392 and 2394 for a second subset of data in other modes of operation. To illustrate the functionality of quasi-aggregated process space 2390 in a first mode of operation, consider that quasi-aggregated process space 2390 can be configured to operate as common process space 2396 as a function of a first type of data. An example of a first type of data is transaction-related data. As used herein, the term “transaction-related data” can refer, at least in some embodiments, to data representing an interaction (or portions thereof) between a participant (or data relating thereto) and another entity in, or in association with, the synthetic environment, whereby the data representing the interaction is processed within a common process space. This can reduce or obviate, for example, interprocess communications. In some embodiments, transaction-related data can include game data that can be exchanged between participants. A transaction also can be a set of tasks constituting an activity that involves one or more participants interacting with a synthetic environment. In some embodiments, transaction-related data can represent an item to be exchanged between a first participant and a second participant, the transaction-related data being used within a common process space to complete the transaction. Regardless of whether the first participant and the second participant are associated with the same or different process spaces, a transaction (or portions thereof) is performed in a common process space, according to at least some embodiments.

One example of transaction-related data includes data representing an exchange of items between participants. For example, consider that a participant possesses a long sword as an item and another participant possesses units of gold as an item, and each participant desires to trade one item for the other. Consider further that prior to initiating the transaction to exchange the items, the data (e.g., as one subset of game data) representing first participant 2370 b and the long sword item reside in, or is associated with, process space 2392, and the data (e.g., as another subset of game data) representing participant 2372 b and the gold item resides in, or is associated with, process space 2394. Transaction server 2342 can be configured to modify an association for the game data to transact the exchange, whereby the association changes from being related to one process space (e.g., one of process space 2392 and process space 2394) to another process space. For example, an association that specifies that first participant 2370 b is linked to an identifier specifying the sword can be changed such that the modified association links the identifier specifying the sword to participant 2372 b. The modification of the association can occur within common process space 2396 to form the modified association, which, in turn, can be stored (e.g., as read-only data) at the process space (and/or game management server) associated with the participant that receives the game data.

Another example of transaction-related data includes data representing an interaction with an entity or object of synthetic environment 2362, such as an NPC. For example, a participant may receive an item from an NPC upon completing a task. Thus, transaction server 2342 can generate associations for the item or any number of items to the participant to transact the transfer of items without accessing database 2382, thereby reducing time that otherwise might be consumed for accessing a database to effect the transaction. Or, the participant may interact with synthetic environment 2362 that generates transaction-related data. For instance, a game rule may allow the participant to pass through or over a portion of the synthetic environment 2362 a limited number of times, after which the participant can no longer pass. Each time the participant passes the portion, common process space 2396 can match the accumulated number of times against data representing a threshold indicating a maximum number of traversals. Transaction server 2342 can then transact a disassociation with data representing permission to traverse the portion. As such, interprocess communications need not be required to enforce game rules.

Yet another example of transaction-related data includes data representing characteristics of an interaction, such as a combat interaction, among participants. For example, a participant with a broad sword item having a specific damage-infliction potential can impart a perceived force (i.e., transmit data representing the force) upon a shield of another participant. In response to the broad sword interacting with (i.e., striking) the shield, the shield can provide for a reaction force that can, in turn, impart a degree of damage to the sword (e.g., the sword might shatter or break if the shield is capable of doing so). In a common process space, data representing a degree of damage of the shield can be exchanged for data representing a degree of damage of the sword. Thus, transaction server 2342 also can be configured to manage and exchange the data that describes or characterizes the exchange of game data for an interaction, as well as the exchange of game data itself (e.g., data representing items in synthetic environment 2362). Transaction server 2342 can be further configured to cache or maintain the modified association (representing the exchanged game data) until the transaction-related data is transmitted and stored in database 2382.

To illustrate functionality of quasi-aggregated process space 2390 in a second mode of operation, consider quasi-aggregated process space 2390 can be configured to operate as at least one of separate process spaces 2392 or 2394 as a function of a second type of data, whereby process space 2392 can be used independently by a participant and need not be used by other participants for the second type of data. An example of a second type of data is environment-related data. As used herein, the term “environment-related data” can refer, at least in some embodiments, to data for facilitating the generation of at least a portion of synthetic environment 2362 via cooperative data exchanges among game management processes 2320, transaction processes 2340, and database management processes 2380. Environment-related data can include data that relates to a single participant and its activity within a portion of synthetic environment 2362. Such data can be associated with a specific participant independent of other participants and their activities. In some embodiments, environment-related data can include game data. In the example shown in FIG. 23, process space 2392 is associated with participant 2370 b and process space 2394 is associated with participant 2372 b. Client 2350 a can use process space 2392 to interact with participant 2370 b, and client 2350 b can using process space 2394 to interact with participant 2372 b. In some instances, game management server 2322 a can be configured to interact with process space 2392 to manage the implementation of participant 2370 b within synthetic environment 2362, and game management server 2322 b can be configured to interact with process space 2394 to manage the implementation of participant 2372 b. Therefore, quasi-aggregated process space 2390 can be configured to implement a process space for a participant (e.g., participant 2370 b) that is independent and distinct from process spaces for other participants (e.g., participant 2372 b).

One example of environment-related data includes range identification (“ID”) data that specify a range of item identifiers with which a game management server, such as game management server 2322 a or 2322 b, is to be assigned. Game management server 2322 b can be configured to manage the assignment of unique identifiers to items, and can be allotted a pool of unique identifiers from which to select and assign an unused identifier to a newly-created item. A newly-created item number may arise when a participant destroys, for example, an NPC and is rewarded an item, which, up to this point, may not have existed in synthetic environment 2362. Game management server 2322 b then can assign a unique identifier to that item from a pool of identifiers. According to some examples, the pool of unique identifiers can include a range of unique 64-bit numbers, each one of which can be unique over both the multiple game management servers, as well as over the synthetic environment. Game management server 2322 b may request range ID data that specifies its range of unique identifiers with which to use (e.g., upon start-up). The request is transmitted from game management server 2322 b to transaction server 2342, and can be in the form of a universal data structure (or derived therefrom). For example, the request can be a message based on a property class object. In response to the request, transaction server 2340 b transmits the request via database management processes 2380 to database 2382, which responds with a message that includes a range of identifiers. Transaction server 2342 retrieves the range of identifiers and conveys the range in a message back to game management server 2322 b. In view of the foregoing, transaction server 2340 b can use quasi-aggregated process space 2390 as a process space independent from other participants to retrieve a range of identifiers from which an identifier will be assigned to the newly-created item for a participant. As the assignment of the identifier to a newly-created item can be made irrespective of other participants and other process spaces, either process space 2392 or process space 2394 can be implemented independently (e.g., more than one participant need not use the same process space).

Another example of environment-related data includes data that describe states of synthetic environment 2362 (e.g., states of plugs and sockets) when, for example, an event server (not shown) comes on-line or otherwise continue an event or activity in synthetic environment 2362. The event may have previously progressed to a point at which the plug and socket data reach specific states prior to termination. For example, an event may be limited to a specific duration, such as 8 pm to 10 pm, that occurs on predetermined days. So, synthetic environment 2362 may have progressed through different states, leaving the plug data and socket data in specific states. To synchronize activities in the synthetic environment to the present states, the event server can request the plug data and socket data from database 2382 (e.g., or an event database) via transaction server 2342. The request by the transaction server can be made irrespective of any specific participant or process space, and, as such, either process space 2392 or process space 2394 can be implemented independently.

Yet another example of environment-related data includes data that describe graphics-related data for rendering computer-generated graphics, and other types of data. Graphics-related data can include data for rendering and/or modeling an image based on, for example, geometry-related data that represent geometries or primitives, such as lines, triangles, and stripes for generating perceptible shapes in synthetic environment 2362. Other graphics-related data also can include data representing textures, shading, refraction, motion blurring, etc., which can be used in cooperation with a game sub-process, such as a physics server (not shown). Game management server 2322 a or 2322 b can be configured to request graphics-related data, such as geometry-related data, from database 2382 to support generation of a participant in the synthetic environment. As such, a request for graphics-related data via transaction server 2342 can be made irrespective of other participants and other process spaces, either process space 2392 or process space 2394 can be implemented (e.g., as a single process space independent from other process space for the second type of data). In some embodiments, a request for environment-related data need not be initiated in response to interaction by clients 2350 a and 2350 b (i.e., need not be initiated by interactions between participants 2370 a and 2370 b and clients 2350 a and 2350 b), and can be initiated by the node processes of synthetic environment generation platform. Note that the functionality of quasi-aggregated process space 2390 to operate as one of process spaces 2392 and 2394 need not be limited to environmental-related data.

As described above, transaction server 2342 can be configured to access database 2382 via database management processes 2380 to transmit and receive data, such as transaction-related and environment-related data. In some embodiments, transaction server 2342 can be configured to select a database management server from a group that includes database management servers 2382 a, 2382 b, and 2382 c. As database management servers 2382 a, 2382 b, and 2382 c may block or otherwise meter accesses to database 2382, transaction server 2342 therefore can distribute requests to access database 2382 over database management servers 2382 a, 2382 b, and 2382 c to reduce the time that a request is in queue. Further, database management servers 2382 a, 2382 b, and 2382 c are configured to communicate with database 2382 via, for example, a specific database language. Thus, transaction server 2342 need not include modules or APIs to communicate via the database language.

FIG. 24 depicts a transaction server configured to perform transaction for a synthetic environment, according to one embodiment. Diagram 2462 depicts transaction server 2420 including a transactional manager 2422, a failsafe manager 2428 and a database (“DB”) server manager 2430. Transactional manager 2422 includes a game data modifier 2424 and a validator 2426. Transaction server 2420 is coupled between game management (“mgmt”) server (“1”) 2410 and game management (“mgmt”) server (“1”) 2412, and one or more database management servers, such as database (“DB”) server 2440, which, in turn, is coupled to one or more databases, such as database 2450. Transaction server 2420 can include or otherwise implement one or processors and/or one or more memories to provide a quasi-aggregated memory space.

Transactional manager 2422 can be configured to manage transactions to exchange data (e.g., game data) between participants associated with different process spaces in a common process space. Transactional manager 2422 can be further configured to receive a message, and to detect whether the message is associated with either transaction-related data or environment-related data, or both. An example of such a message is a request originating from a process space associated with a participant to exchange game data (i.e., within a common process space). For example, consider that a message that includes transaction-related data is contained in a transaction request (“transreq”) 2418 message originating from a participant (“A”) 2470, which can be associated with game management server 2410 and a process space 2411 a. Transaction request 2418 can include data specifying the identity of a participant, such as participant 2470, as well as the identity of game data 2471 (e.g., data representing sword) to be disassociated with process space 2411 a and game data 2473 (e.g., data representing gold) to be associated with process space 2411 a. In the example shown, participant (“A”) 2470 and participant (“B”) 2472 exchange messages 2414 that include information for initiating the transaction. For example, messages 2414 can include data representing an offer from participant (“A”) 2470 to participant (“B”) 2472 to enter into a trade, data representing suggested items to exchange, data representing acceptance by both parties (i.e., both parties confirm their commitment to the trade), and other transaction-related data. In FIG. 24, participant 2472 can be associated with game management server 2412 and a process space 2411 b, which includes game data representing 2473.

Game data modifier 2424 is configured to determine game data 2471 and 2473 (and/or associations thereto) to be exchanged between participants 2470 and 2472 in a transaction, and to determine that participants 2470 and 2472 are committed to exchange the game data. When the transaction is determined to be valid and can be completed for the participants (and requests), game data modifier 2424 is configured to disassociate game data 2471 with process space 2411 a, and associate game data 2713 with process space 2411 a, thereby transacting the exchange. The disassociation of game data 2471 and the association of game data 2473 respect to process space 2411 a can occur in a common process space of a quasi-aggregated process space. After the exchange, transactional manager 2422 can update process space 2411 a to include game data 2473 as read-only data. Note that in some embodiments, the transaction-related data can be stored in a temporary memory (“TempMem”) 2416 associated with one of the game management servers, such as game management server 2410. Temporary memory 2416 stores data representing that participant A is to lose (“−”) a sword and is to gain (“+”) x amount of gold, with other data representing the counterpart of the transaction for participant B. Once both participant (“A”) 2470 and participant (“B”) 2472 confirm the transaction, transaction request 2418 is generated to include the data from temporary memory 2416. Note that temporary memory 2416 need not be accessible by either participant (“A”) 2470 or participant (“B”) 2472, in various examples. Note further that temporary memory 2416 can be disposed anywhere in a synthetic environment generation platform.

Validator 2426 is configured to determine whether to the exchange of game data 2471 and 2473 is a valid action. An action, such as a transaction, is valid if the transaction conforms to rules that govern the transaction. In operation, validator 2426 can evaluate whether the transaction can complete for each participant without violating one or more rules. One example of a rule is a requirement that a specific amount of memory needs to be available to store an acquired item (or associations therewith). If validator 2426 determines that there is not enough memory to complete a transaction, then the action can be determined to be invalid. In some instances, validator 2426 can generate a signal representative of the invalid nature of the transaction. Responsive to the signal, game data modifier 2424 forgoes modifying associations of the game data, thereby nullifying the transaction. An example of another rule is a requirement that one or more of the participants need to be of a certain stature (e.g., associated with an amount of experience or points in relation to the synthetic environment) for a transition to be deemed valid. If this rule is transgressed, then the transaction can be nullified. Should various aspects of participants and the transaction comport to the rules, then validator 2426 can generate a signal representative of the valid nature of the transaction.

Failsafe manager 2428 can be configured to execute (or permit) an exchange of game data 2471 and 2473 between the participants or to nullify the exchange of the game data 2471 and 2473. In particular, failsafe manager 2428 monitors the transaction to ensure that transaction is completed for each participant and that data of the transaction persists in association with the synthetic environment (e.g., the data is stored in database 2450). Failsafe manager 2428 can manage transactions among participants to ensure the transactions are atomic. In some examples, failsafe manager 2428 can operate to ensure that all parts of a transaction occur, or all do not occur, thereby guaranteeing that game data 2471 and 2473 stored in database 2450 are not updated unless all parts of the transactions succeed, thereby reducing loop-holes for participants to seek unjust enrichments. Transaction server 2420 can be the game authority that ensures that an activity is completed correctly for both participants 2470 and 2472, or is failed by both participants 2470 and 2472.

Database server manager 2430 can configured to coordinate the persistent storage of the game data 2471 and 2473 in database 2450. In particular, database server manager 2430 selects a database server, such as database server 2440, to manage the storage of transaction-related data specifying the exchanged items. In some embodiments, database server manger 2430 can select database server 2440 in, for example, a round-robin fashion. Once selected, database server manager 2430 and database server 2440 exchange messages 2432 via message interface 2442, the messages specifying data to be stored in or retrieved from database 2450. In some embodiments, message interface 2442 is a universal message interface configured to communicate messages 2432 as a universal message, examples of which are described above. In some embodiments, the universal message is associated with a universal data structure (e.g., a message based on a property class data arrangement). Database server manger 2430 can include a database driver that is configured to communicate messages 2446 with database 2450, whereby messages 2446 can be in a form that is compatible with database 2450. For example, the database driver can be configured to implement database-specific interface, such as an Open Database Connectivity (“ODBC”) interface or driver, or any other equivalent interface or driver that can implement database access functions in an API.

FIG. 25 depicts a synthetic environment generation platform configured to generate interfaces to perform transactions using a quasi-aggregated process space, in accordance with at least one embodiment of the invention. Synthetic environment generation platform 2540 is shown to include an interface generator 2541, a transaction server 2550 and a database 2560. Interface generator 2541 is configured to generate data representing interfaces 2502 and 2504 that can be presented at (e.g., viewable on) a display device for participant (“A”) 2570 and participant (“B”) 2572, respectively. Examples of a display device include a television display, a mobile phone interface, a handheld device display, etc. Interface generator 2541 can generate an input portion 2512 of interface 2502 configured to accept data representing an offer of an item, an output portion 2514 of interface 2502 configured to present another item that can be exchanged for the item, and an input portion (“C”) 2516 of interface 2502 configured to accept an indication that the transaction is confirmed by participant 2570. Similarly, interface generator 2541 can generate an input portion 2522 of interface 2504, an output portion 2524 of interface 2504, and an input portion (“C”) 2526 of interface 2504, each of which can be configured to provide similar functionality as described for interface 2502. Input portions 2512, 2516, 2522, and 2526 can be input fields, input buttons, etc., for accepting user input, and further can generate data signals for communicating messages with synthetic environment generation platform 2540. In some examples, output portions 2514 and 2524 are portions for displaying proposed items to trade, and can optionally be configured to accept input specifying agreement or rejection of the item.

To illustrate the functionality of interfaces 2502 and 2504, consider the following example. Participant 2570 initiates contact via messages 2534 with participant 2572 to inquire whether there is interest in trading items during phase 1, as indicated by encircled number “1.” Participant 2572 responds via messages 2532 to indicate interest during phase 2, as indicated by encircled number “2.” For this example, note that subsequent phases are indicated by a corresponding encircle number. In other examples, one or more phases can occur in parallel or in series with each other, or can be omitted or supplemented with other phases not shown. Further to the example, participant 2570 specifies an offer to trade a sword by inputting data 2511 into input portion 2512 in phase 3. Responsive to participant 2570 inputting data 2511 into input portion 2512, messages 2534 can be generated. Messages 2534 cause data 2523 representing the sword to present the sword in portion 2524 as an item participant 2572 will receive after the transaction is completed. Next, participant 2572 returns an offer to trade an amount of gold for the sword by inputting data 2521 into input portion 2522 in phase 4, and, in response, messages 2532 can be generated. Messages 2532 can cause data 2513 representing the gold to present the gold as an item participant 2570 will receive after the transaction is completed.

Once both participants 2570 and 2572 input data representing confirmation of the transaction into input portions 2516 and 2525, respectively, a transaction request 2542 is generated and transmitted to transaction server 2550 during phase 5. Transaction server 2550 implements a quasi-aggregated process space (not shown) to perform the transaction. Further, transaction server 2550 can modify associations during phase 6 for each of the participants in database 2560. For example, consider that a grid 2562 represents a number of memory locations that includes items associated with participant 2570 and that a grid 2564 represents a number of memory locations that includes items associated with participant 2572. Thus, grids 2562 and 2564 can serve as repositories the inventories of the participants. The transaction performed by transaction server 2550 can cause data 2463 representing a sword to be stored at memory location 2568, thereby associating the sword with participant 2572. In some examples, an association for the sword can be modified to relate to participant 2572 (e.g., a pointer can be modified to point to participant 2572 rather than participant 2570). In one example, a 64-bit item identifier representing the sword can be transferred from being associated with grid 2562 to begin associated with grid 2564. Similarly, transaction server 2550 can modify an association for data 2465 representing an amount of gold relation such that the association is changed from being related to grid 2564 to grid 2562. In some embodiments, data 2465 representing an amount of gold can be stored in grid 2562 to change its association from participant 2572 to participant 2570. Transaction server 2550 can then generate messages 2544 in phase 7 to store the updated data (e.g., as read-only data) in separate process spaces (not shown) should participants 2570 and 2572 be associated with different process spaces (e.g., and/or different game management servers).

FIG. 26 is a diagram showing examples of universal data structures that can be used to perform transaction in accordance with at least one embodiment of the invention. Universal data structure 2602 is shown as a property class object 2604 identified by identifier 2601 (i.e., “Trade Request” as a transaction request) having, for example, a class identifier (e.g., a class ID) of “85,” as an example. Property class object 2604 includes an arrangement of data that includes attributes 2606 and 2626. Attribute 2606 specifies data for one participant as the source participant that initiates the transaction. Attributes 2608 specify data that represent one or more items associated with the source participant to be subject to the trade request. As depicted, attribute 2607 specifies that item identifier 1001 (e.g., representing a sword) is to be subject to the trade request. Attribute 2626 specifies data for the other participant as the target participant that is the target of the transaction. Attributes 2618 specify data that represent one or more items associated with the target participant to be subject to the trade request. As depicted, attribute 2617 specifies that item identifier 3199 (e.g., representing an amount of gold divisible into units, such as gold coins) is to be subject to the trade request.

Universal data structure 2652 is shown as a property class object 2654 identified by identifier 2651 (i.e., “Item Entry” as an item to be exchanged) having, for example, an item entry identifier of “3199,” as an example. Property class object 2654 includes an arrangement of data that includes attributes 2660, 2662, and 2664. Attribute 2660 specifies data representing a 64-bit unique identifier (“ItemID”) associated with the item (e.g., gold) to be traded. Attribute 2662 specifies data representing a number of units (“StackCount”) of gold that is subject to the trade (e.g., any number of coins, such as 10 coins), where “xx” represents the number. Attribute 2664 specifies data representing an item class ID (“ItemClassId”), where “yy” represents the item class ID.

FIG. 27 is a diagram showing an example of universal message interface that can be used to generate a universal message as a transaction request in accordance with at least one embodiment of the invention. Universal message interface 2799 includes a common data representation converter 2730 configured to encapsulate data (e.g., data of various data types) based on or in the form of a universal data structures, such as a property class object, into one or more messages 2750, whereby messages can form a portion of a “common data representation” (“CDR”) stream from a transmitter (e.g., a game management server and/or a temporary memory) to a receiver (e.g., a transaction server). In some embodiments, common data representation converter 2730 can be configured to insert units of data from universal data structures 2602 and 2652 of FIG. 26 into message 2750. For example, a CDR insertion process 2732 can be configured to insert unit of data (“85”) 2702 into portion 2760 a of message 2750. Likewise, CDR insertion processes 2734 and 2736 can be configured to insert units of data (“1”) 2704 and (“vec”) 2706 into respective portions 2760 b and 2760 c of message 2750. In this case, unit of data (“vec”) 2706 indicates that the attribute specifying the source participant is a “vector” of data. Further, a CDR insertion process 2738 can be configured to insert unit of data (“3199”) 2708 into portion 2760 d of message 2750, and a CDR insertion process 2740 can be configured to insert unit of data (“0×1FFFFFFFFFFFFFFF”) 2710 into portion 2760 e of message 2750. Also, CDR insertion processes 2742 and 2744 can be configured to insert units of data (“xx”) 2712 and (“yy”) 2714 into respective portions 2760 f and 2760 g of message 2750. Note that a universal message interface at the receiving end (e.g., at the transaction server) can implement similar CDR processes, but by extracting data rather than inserting data.

FIG. 28 illustrates an exemplary computer system suitable for initiating and/or performing any portion of a transaction in a synthetic environment, according to at least one embodiment of the invention. In some examples, computer system 2800 can be used to implement computer programs, applications, methods, processes, or other software to perform the above-described techniques and to realize the structures described herein. Computer system 2800 includes a bus 2802 or other communication mechanism for communicating information, which interconnects subsystems and devices, such as one or more processors 2804, system memory (“memory”) 2806, storage device 2808 (e.g., ROM), disk drive 2810 (e.g., magnetic or optical), communication interface 2812 (e.g., a modem, Ethernet card, or any other interface configured to exchange data with a communications network or to control a fabrication machine), display 2814 (e.g., a visual output device, such as a CRT or LCD, a tactile output device or an auditive output device), input device 2816 (e.g., keyboard), and pointer cursor control 2818 (e.g., mouse or trackball).

According to some examples, computer system 2800 performs specific operations in which processor 2804 executes one or more sequences of one or more instructions stored in system memory 2806. Such instructions can be read into system memory 2806 from another computer readable medium, such as static storage device 2808 or disk drive 2810. In some examples, hard-wired circuitry can be used in place of or in combination with software instructions for implementation. In the example shown, system memory 2806 includes modules of executable instructions for implementing an operation system (“O/S”) 2832, and an application 2836, which include a transaction manager module 2838 including a game data modifier module 2839 and a validator module 2840, a failsafe manager module 2841, and a database (“DB”) server manager 2842, each of which can provide functionalities described herein. System memory 2806 also can include one or more of the following: a process space 2850, another process space 2852, and/or a common process space 2854, each of which can provide functionalities described herein.

The term “computer readable medium” refers, at least in one embodiment, to any medium that participates in providing instructions to processor 2804 for execution. Such a medium can take many forms, including but not limited to, non-volatile media, volatile media, and transmission media. Non-volatile media includes, for example, optical or magnetic disks, such as disk drive 2810. Volatile media includes dynamic memory, such as system memory 2806. Transmission media includes coaxial cables, copper wire, and fiber optics, including wires that comprise bus 2802. Transmission media can also take the form of electromagnetic, acoustic or light waves, such as those generated during radio wave and infrared data communications.

Common forms of computer readable media includes, for example, floppy disk, flexible disk, hard disk, magnetic tape, any other magnetic medium, CD-ROM, any other optical medium, punch cards, paper tape, any other physical medium with patterns of holes, RAM, PROM, EPROM, FLASH-EPROM, any other memory chip or cartridge, time-dependent waveforms, or any other medium from which a computer can read instructions.

In some examples, execution of the sequences of instructions can be performed by a single computer system 2800. According to some examples, two or more computer systems 2800 coupled by communication link 2820 (e.g., links to LAN, PSTN, or wireless network) can perform the sequence of instructions in coordination with one another. Thus, various method portions and portions of executable instructions can be distributed over multiple locations. Computer system 2800 can transmit and receive messages, data, and instructions, including program code (i.e., application code) through communication link 2820 and communication interface 2812. Received program code can be executed by processor 2804 as it is received, and/or stored in disk drive 2810, or other non-volatile storage for later execution. In one embodiment, system 2800 (or a portion thereof) can be integrated into an image capture device or a display device for matching colors.

In some examples, the methods, techniques and processes described herein may be performed and/or executed by executable instructions on computer processors, for which such methods, techniques and processes may be performed. For example, one or more processors in a computer or other display controller may implement the methods describe herein by executing software instructions in a program memory accessible to a processor. In some embodiments, the term “processor” can refer, at least in some embodiments, to executable instructions (partially or entirely). Thus, a processor as described herein can be composed of entirely executable instructions configured as a software processor, such as a virtual processor, java machine, or the like. Additionally, the methods, techniques and processes described herein may be implemented using a graphics processing unit (“GPU”) or a control computer, or field-programmable gate array (“FPGA”) or other integrated circuits coupled to the display. These methods, techniques and processes may also be provided in the form of a program product, which may comprise any medium which carries a set of computer-readable instructions which, when executed by a data processor, cause the data processor to execute such methods, techniques and/or processes. Program products, may include, but are not limited to: physical media such as magnetic data storage media, including floppy diskettes, and hard disk drives; optical data storage media including CD ROMs, and DVDs; electronic data storage media, including ROMs, flash RAM, non-volatile memories, thumb-drives, or the like; and transmission-type media, such as digital or analog communication links, virtual memory, hosted storage over a network or global computer network, and networked-servers.
